PROBLEM TO BE SOLVED: To provide a touch panel structural material to be used for a large-area touch panel, at a low cost, while improving reliability and visibility.SOLUTION: A touch panel structural material is obtained by forming fine lines on a laminate formed of a transparent substrate and a conductive metal layer by photolithography and forming a coating film with silver which is a metal more precious than a conductive metal. The conductive metal is copper, and has a thickness of 0.1 to 5 μm. A linewidth is 1 to 3 μm.SELECTED DRAWING: Figure 3 |
